` Specification forming part of' Letters" Patent No. 192,800, dated uly, 1877; application tiled March 31, i877.

To all whom it may concern: V

Be it known that we, LEVI WERTENBER- GER. and GEORGE W.'AMISS, of Laketon, in

the county of Wabash and State of Indiana, have invented a new and valuable Improvement in Sulky Plows and Gultivators; .and

we do hereby declare that the following is a` 'plow and cultivator, and Fig. 2 is a plan View thereof.

This invention relates to wheel-cultivators; and 4consists 1n the construction and arrangev ment hereinafter fully set forth.

In the accompanying' drawings, A desig- Dates the two transporting-wheels of our cultivator, and B the arched axle vconnecting them. The verticalends of said axle are of metal, and, have twoor more perforations, b, arranged in vertical series, so as to allow said axle to be, adjusted upward or downward, the spindles A', 4on which said wheels A turn, being passed through the upper or lower pair of said holes, according to said adjustment. The inner ends of said spindles are screw-threaded to receive nuts b', whereby said spindles are C designates a draft-tongue and reach, the

n rear end of which is attached to said axle, and which also supports a rigid front cross-bar,

D. To the front of said cross-bar D a doubletree, E, is attached, having whiffletrees E' E', and on the rear of said cross-bar are four brackets or devises, F, which serve as pivots for the' front ends of four beams, Gr, arranged two on each side of said reach or tongue. To the rear ends of said beamsare pivoted the upper ends of standards H, which `are provided attheirlower ends with plow-points I. Said standards are provided with a series of ho1es, '11, arranged in longitudinal series, so

that said plows may be raised or lowered at will. The two outer beams G are braced by metal plates or braces J, which are attached at their rearV ends to the inner sides of said bealns, and pivoted at their front ends" to bent rods J on bar D. When lowered for. work, all of said beams G rest upon axle B.

K designates the drivers seat, which is supported by a horizontal seat-bar, E', that Y is held to axle B and reach G by eyes or staples 7c k. Said seat maybe moved backward or forward at pleasure.

Each standard H is braced by a curved bar, L, that extends `from the lower part of the 4front of said standard upward and `forward through a slot, l, in the beam, to which said standard is pivoted. Said brace-bars L are provided with perforations l', arranged in series in the upper front end-of each bar, allow? ing the fastening hook or pin to be shifted from one "hole to another, so as to permit the adjustment of the plow-points I upward or downward.

M designates two levers or operating-arms, formed upon the inner ends of two rock-shafts, M1, which are journaled in lugs or brackets m on the back of axle B. Each shaft M1 is provided with two short arms, m1, which form` toggle-connections with 'two bars or arms, M2, and support (when said toggles are straightened) the two beams G, that are on one side of the machine. By turning forward either lever or'arm M, the pair of plows l onits side of the machine are raised out of operation.

vAs these levers M are quite close to the drivers seat, either one of them may be turned forward or backward, at will, without inconvenienee. y

For operating both levers together, so as to raise all the plows out of contact with the ground, we employ a wire frame, N, that is pivoted to lugs on the back of axle B,and bent at the tcp so as to engage with levers M. By turning said frame forward, all-the plows are lifted at once; by turning it backward, the plows are let down upon the ground again. BarsM2 are provided with two or more holes, m2, for varying the length and play of the toggles. Additional braces may be usedfor strengthening the various parts of the machine. The two inner. standards H are provided' with feos-,rests H', whereby einher pair into the soil.

What we claim as new, and by Letters Patent, is-

' 1. Theeombination o f `pivoted frame N with levers M, shaifts 'ML ,pivoted beams G, and toggle-connections, substantially as and for the purpose set forth. l

desire to secure v 42. The combination ofpivvoted beamsGwith braces J andvL, standards H, rock-shaft M1,

und adjustable :togg-les,substantietuyas and 'orithe purpose .set forth. Y

In testimony that We claim the above we have hereunto subscribed our names in the presence of two witnesses.
